Are you dancing? Having a seizure? What's going on here?

Be prepared because at any moment they will bust out skate maneuvers on the flat ground no matter where you may be at the given time.  They may try to come up with excuses or ignore the fact that you're staring at them like they have lost their mind but they are planning out what tricks they are going to try during their next session. They may appear to be, and cover it up by saying they are dancing poorly but they are not...trust me. They don’t even realize it most times, at least I don’t think so because they become oblivious to the outside world when they get lost in their head while thinking about skating and I think their body just naturally follows without realizing.

 

I've been standing at a hostess booth at a fairly nice restaurant and he's just started doing stalls on the stairs, spinning around like a maniac, or grinding on nothing.  You can try your best to keep them focused but you'll realize you just have to let them get in a few tricks. 

 

Just try and keep them away from steps or any sort or ledges when you're taking a stroll or trying to have a real conversation with them.  Just lead them away in a different direction.  Also realize that this is almost impossible as being a rollerblader has also made their feet automatically attracted to such things.
